bge Ierr rate increase from 5.3R - 6.1R
Hello I recently updated two production servers from 5.3 to 6.1 via cvsup and buildworld. Since the upgrade I've seen an increase in the number of Input packet errors reported on the bge cards in on both boxes. One is a HP DL360g3, the other is a HP DL380g3. Both have a pair of 2.8GHz Xeons with a SMP kernel. So - was the old driver previously underreporting, is the new one over-reporting/causing the error rate or is it something else? Cables and cabling have not changed and the pickup in number of errors is quite distinct. I monitor the nightly 'periodic daily' phone homes closely. Example from the DL380g3. The 5.3-6.1 upgrade was on 8 November. 58,000 errors in 1 month compared to 2 errors in 1 year with 5.3. Network interface status: NameMtu Network Address Ipkts IerrsOpkts Oerrs Coll bge0 1500 Link#1 00:0f:20:f6:**:** 1344182650 58292 2701993948 0 0 bge0 1500 192.168.**/25 **1344176611 - 2701984851 - - bge1* 1500 Link#2 00:0f:20:f6:**:**0 0 0 0 0 lo0 16384 Link#3 69549 0 69549 0 0 lo0 16384 your-net localhost69549 - 69549 - - A couple of weeks ago I turned off tx and rx check summing on this box as I gathered from googling it might be contributing. That had no effect. Upon further investigation it appears six other boxes with bge ports (mostly HP DL360g4) running 6.1 started reporting errors when moved to 6.1. As they do only a small fraction of the traffic that the above box does I hadn't noticed it. This box (a UP HP DL360g4) is on a completely different network, different switch, cabling etc. Again, prior to 6.1 it had never reported an error in 18 months of service.

malloc(0) returns 0x800 on FreeBSD 6.2 ?
i was debugging a program on FreeBSD 6, and much to my
surprise, i noticed that malloc(0) returns 0x800, as shown
by this program:
more a.c
#include stdio.h
int main(int argc, char *argv[])
{
char *p = malloc(0);
printf( malloc 0 returns %p\n, p);
}
cc -o a a.c
./a
malloc 0 returns 0x800
if you look at the source this is indeed clear - internally
the 0x800 is ZEROSIZEPTR and is set when a zero length is
passed to malloc() unless you have malloc_sysv set.
The thing is, i don't know if this behaviour is intentional or not,
but certainly is not documented -- the manpage documents
something totally different (in the section for the 'V'
MALLOC_OPTION, see below).
TUNING
...
V Attempting to allocate zero bytes will return a NULL pointer
instead of a valid pointer. (The default behavior is to make a
minimal allocation and return a pointer to it.) This option is
provided for System V compatibility. This option is incompatible
with the ``X'' option.
So what should we do with this ? Just fix the manpage or fix the
code ? This behaviour is likely to break quite a few things...

Re: bge Ierr rate increase from 5.3R - 6.1R
Greg Eden wrote: Hello I recently updated two production servers from 5.3 to 6.1 via cvsup and buildworld. Since the upgrade I've seen an increase in the number of Input packet errors reported on the bge cards in on both boxes. One is a HP DL360g3, the other is a HP DL380g3. Both have a pair of 2.8GHz Xeons with a SMP kernel. It would be quite useful at this point if you could update a box or two to the RELENG_6_2 code base so that we can see if this problem is solved in the latest release candidate. If it is, your problem is solved, and if it's not, you're a lot closer to the point where we can usefully assist you.

Re: malloc(0) returns 0x800 on FreeBSD 6.2 ?
On Mon, 11 Dec 2006 12:25:44 -0600 Dan Nelson [EMAIL PROTECTED] wrote: The FreeBSD 6.x behaviour is slightly against POSIX rules that state all successful malloc calls must return unique pointers, so the 7.x malloc silently rounds zero-size mallocs to 1. Ideally malloc would return unique pointers to blocks of memory set to MPROT_NONE via mprotect() (you could fit 8192 of these pointers in an 8k page), to Could you, really? I'm not a language lawyer, and this is a language-lawyer question, but I would have expected that the maximal alignment rule would prevent you from allocating more than 512 or 1024 unique, valid pointers in a page. Perhaps there is no alignment requirement on a zero-byte object? Just curious. I don't care about the actual implementation, and I thought that handing out a special MPROT_NONE page was a good idea... prevent applications from using that byte of memory.
